Usage

STableViewController is not very useful on its own. It has to be subclassed to apply your custom
views and adjust any behavior. To get started quickly, you may include these files for reference:

DemoTableViewController - subclass of STableViewController. This declares what views
to use for pull-to-refresh and load-more. Also includes samples on what methods to override
for data loading and a sample customization to interact with the header and footer views
depending on the situation.

DemoTableHeaderView - the view used for pull-to-refresh

DemoTableFooterView - the view used for load-more

You may also opt to implement your own subclass for STableViewController and use your own
views for pull-to-refresh and load-more.

See STableViewController.h for more information on the methods available.
